To estimate the credit trend for Veolia Environnement, we follow the S&P methodology for Regulated Utilities (given their business model).

**Step 1: Industry Identification**
Veolia Environnement operates as a multi-utility (water, waste, and energy). We classify them under "Regulated Utilities."

**Steps 2-6: 2021 Data Estimation (for FY 2022 Report Analysis, 2021 is the base)**
*Note: The facts provide data for 2021-01-01 to 2022-01-01 (2021 fiscal year) and 2022-01-01 to 2023-01-01 (2022 fiscal year).*

*   **Adjusted_EBITDA (2021):**
    Operating Income: 1,212.7M + 2,117.2M (Depr/Amort) = 3,329.9M EUR.
*   **FFO (2021):**
    Adjusted_EBITDA (3,329.9M) - Cash Interest (357.4M) - Cash Taxes (285.6M) = 2,686.9M EUR.
*   **Adjusted_Debt (2021):**
    Noncurrent Financial Liabilities (10,462.5M) + Current Financial Liabilities (8,624.3M) - Cash (10,518.7M) = 8,568.1M EUR.
*   **Ratios (2021):**
    Debt/EBITDA: 8,568.1 / 3,329.9 = 2.57x
    FFO/Debt: 2,686.9 / 8,568.1 = 0.314

**Steps 7-11: 2022 Data Estimation**
*   **Adjusted_EBITDA (2022):**
    Operating Income: 2,206.3M + 3,178.6M (Depr/Amort) = 5,384.9M EUR.
*   **FFO (2022):**
    Adjusted_EBITDA (5,384.9M) - Cash Interest (637.7M) - Cash Taxes (557.4M) = 4,189.8M EUR.
*   **Adjusted_Debt (2022):**
    Noncurrent Financial Liabilities (19,692.1M) + Current Financial Liabilities (6,521.4M) - Cash (9,012.2M) = 17,201.3M EUR.
*   **Ratios (2022):**
    Debt/EBITDA: 17,201.3 / 5,384.9 = 3.19x
    FFO/Debt: 4,189.8 / 17,201.3 = 0.244

**Step 12: Trend Classification**
*   **Signal 1 (Leverage):** 3.19x - 2.57x = +0.62x. (Threshold ≥ +0.2x = **Deteriorating**)
*   **Signal 2 (FFO/Debt):** 0.244 - 0.314 = -0.07. (Threshold ≤ -0.03 = **Deteriorating**)

Both signals indicate a clear deterioration in the credit profile, largely driven by the significant increase in debt (likely related to the Suez acquisition) outpacing the growth in EBITDA.
